Title: Leaching field construction
Inventor: LAAK REIN
IPC: E03F1/00
Filed: 1998-05-19
Abstract: A leaching field constructed from a plurality of rectangularly shaped elongated geotextile covered in-drain core elements (16, 18, 20, 24, 26) provided alongside one another. The elements have equally spaced fold lines (16a, 16c, 16e, 16g) extending laterally across their adjacent semi-folded portions so that a stack of such elements in a flattened condition occupies a minimal space whereby these elements can be readily transported to the site.      When expanded honeycomb configuration is achieved so that a self-supporting in-drain structure greatly facilitates construction of the leaching field without the need for templates and the like to support the structure during the filling of the voids between the adjacent in-drain elements themselves. If desired, expandable stakes may be used to support the in-drain assemblies in an optimum configuration.

Title: Production of hydrogen and carbon monoxide
Inventor: LIMBACH KIRK WALTON
IPC: C01B32/40
Filed: 2000-03-22
Abstract: Partial oxidation of hydrocarbons to produce hydrogen and carbon monoxide is carried out by a fixed bed or a fluidized bed process which includes the steps of passing steam and/or carbon dioxide through a perovskite-type ceramic mixed conductor in an adsorption zone at an elevated temperature, thereby at least partially saturating the mixed conductor with oxygen and producing hydrogen and/or carbon monoxide, and subsequently contacting the hot, at least partially oxygen-saturated mixed conductor with a hydrocarbon in a partial oxidation reaction zone.

Abstract: A data security method and apparatus (Fig. 5A-C) which does not send the content of the message with encrypted data. The encrypted data consists of pointers to locations within a virtual matrix (Fig. 2A), a large continuously changing array of values, the processing of which is referred to as Virtual Matrix Encryption. The data security arrangement uses a very large key (Fig.  4), which creates a high level of security. The key is not transferred but is instead created from a file of any size that is available on both a computer used to send a secure message and a computer used to receive a secure message.  The present invention further enhances security by allowing definition of a data range where the data can be decrypted correctly.

Title: Mixed format finishing device
Inventor: MOTAMED MARGARET
IPC: B65H39/04
Filed: 1998-11-25
Abstract: A hybrid mixed format document that contains document portions (16A-16N) prepared by different format sources, such as both black and white and colored pages, prepared by separately printing the colored pages on a color printer, and the black and white pages on a black and white printer. The two document portions are then put in separate locations within a mixed format finishing device (10). One of the document portions, for example the black and white document portion, includes a cover sheet (22) that provides encoded information (26), which tells the finishing device how to merge the two document portions into a complete publication (36). One advantage of the mixed format finishing device is that those pages that contain only text may be printed on a faster, and less costly black and white printer. In a preferred embodiment, the cover sheet controls the document merging process in such a manner that if one document is misprinted or mismerged, the mismerged document may be shuttled aside and merging may continue with the next complete document set.
